Abstract
An improvement in and relating to powered driven and wheeled vehicles; more specifically, to improvements in wheel brake systems of such vehicles, wherein a condenser will charge in a voltage responsive to the wheel rotation at the commencement of a brake applying operation, and the discharge speed (or discharge voltage) of the condenser is made variable in response to foot brake pedal pressure. A comparison is made between this voltage and a wheel rotation-responsive voltage during the braking operation and derived through a separate part of the electronic circuit concerned. When the latter voltage is higher than the former voltage, the wheel cylinder pressure is increased through the intermediary of a pressure intensifier, until the both voltages are brought into coincidence with each other. In this way, the liquid pressure as applied to the wheel cylinder is made always to response to the pedal pressure.
